Children and Convergence Insufficiency

Convergence insufficiency is present in 1 out of every 20 children suggesting that in a typical classroom 1-2 children may have this condition. Studies has demonstrated that children with this problem are likely to experience performance related symptoms (e.g. loss of place, loss of concentration, re-reading the same line, reading slowly, trouble remembering what was read or feeling sleepy) as well as eye related symptoms (e.g. blur, headache, diplopia, or eye strain).

In addition, The Convergence Insufficiency Treatment Trial (CITT) studied parent concern about school performance in children with convergence insufficiency. The study looked at parents' perceptions of the frequency of problem behaviors that their child may exhibit when reading or performing schoolwork (such as: difficulty completing work, avoidance, and inattention). The survey was administered to the parents of 221 children 9-17 years old with symptomatic convergence insufficiency prior to enrolling into the Convergence Insufficiency Treatment Trial and to 49 children with normal vision. Parents of children with CI reported a higher frequency of behaviors that may interfere with their children's completion of school work and academic progress. In addition, parents of children with CI reportedly “worry” more about their children's school performance.
